IMPROVEMENT IN RANGES.

Specification forming part of Letters Patent No. 38,952, dated June 23,1863; antedated April 29, 1863.

To aZZ whom it may concern:

Be it known that I, SAMUEL PIERCE, of the city of Troy, county ofRensselaer, and State of New York, have invented certain new and usefulImprovements in Kitchen-Ranges; and I do hereby declare that thefollowing is a full, clear, and exactdescription of the same, referencebeing hereby had to the accompanying drawings, and to the letters ofreference marked thereon, which drawings make a part of thisspecification.

Like letters represent and refer to like and corresponding parts.

Figure 1 shows the range in condition for use. Fig. 2 is a verticalsection through the center from front to rear and on the line of 1, Fig.3. Fig. 3 is a vertical section lengthwise of the range and the line ofm, Fig. 2. Fig. 4. is a top view on the line of :20, Fig. 2.

The nature of my improvement consists in the employment and combinationof a reservoir and feeder to hold and supply coal to the fire chamber ator near the rear end of the saidphamber and between the ovens of therange, so that a continuous and regular supply of coal is had ascombustion is carried on in the fire box or chamber by means thereof.

To enable others to make and use my improved kitchen-range, I will hereproceed to describe the construction and operation of the same, which isas follows, to wit I construct a reservoir and supply-feeder, a, Figs. 1and 2, of iron of any strength desired, and in width the same as that ofthe fire box or chamber to be supplied with coal. I place this reservoirand feeder at or near the back part of the range, as seen at Fig. 2,which is of any height or capacity required. The coal is admitted tothis reservoir through the door 1" at the top thereof, Figs. 2 and 3,which is then closed perfectly tight.

5- Figs. 2, 3, and 4, is fire-brick back, somewhat in the form of atriangle with an upper concave surface, and serves to guide the coal asit passes into the fire-chamber d. This brick back extends the fullwidth of the said fire-chamber.

f Figs. 2, 3, and 4, is a water-back, having tubes extending in eachdirection, as seen atp This back extends the 'When the coal in the saidfire-chamber d is consumed and reduced to ashes, by shaking thefire-grate o, the ashes fall from the said chamber and fresh coal enterstherein fromthe said reservoir and feeder in an ignited state, and thuscombustion goes on in an even and perfect manner. The draft iscontrolled by the ordinary dampers in the front doors, or dampers in thesmoke-pipes.

Having thus described my improvements in ranges, what I claim, anddesire to secure by Letters Patent of the United States, is

The supplying of the fire-chamber d, at the rear end thereof, by meansof the reservoir and feeder a, in combination with the triangle concavefire-brick back b and the fire-chamber d, in the manner substantially asherein de- 7 scribed and set forth.

In testimony whereof I have, on this 26th day of September, 1862,hereunto set my hand.
